A community-based study of intention to use HIV self-testing among young people in urban areas of southern Ethiopia.

In sub-Saharan Africa, young people are at high risk of HIV infection, representing nearly 4 out of 5 new infections. HIV self-testing (HIVST), a new and proactive testing scheme that involves self-collection of a specimen and interpretation of results, is deemed potentially helpful for increasing testing amongst population groups like young people who do not frequently use routine testing services. This study assessed young people's intention to use HIVST in urban areas of southern Ethiopia drawing on the Theory of Planned Behaviour. A community-based cross-sectional study was conducted with 634 participants aged 15–24 years from six town administrations of two zones in January to February 2023. The participation rate was 634/636 yielding 99.7%. The OraQuick HIVST kit was demonstrated to young people recruited in a door-to-door survey with a face-to-face interview using an electronic questionnaire in a mobile phone-based application. Intention to use HIVST was measured from a 6-point Likert scale with scores of agreements ranging from 1 to 6. Descriptive statistics and ordinal logistic regression analysis were done using STATA version 18. Most of the participants agreed that they would use HIVST if it was available (86.3% agreeing or strongly agreeing). Interestingly, young people who perceived themselves at some to high risk were 0.51 times less likely to be in the higher order of intention to use when HIVST is available to them than those who perceived themselves at no to low risk. Intention to use HIVST increased by a factor of 1.29, 1.84 and 2.35 for every one-unit increase on the mean favourable attitude, perceived behavioural control, and acceptability scores, respectively. The majority of young people intended to use HIVST. Young people's perceived behavioural control, and acceptability of HIVST affected their intention to use. Intention and subsequent use of HIVST can be enhanced through an understanding of the role of risk perception and positive attitude, confidence to perform and acceptance of the test. Implementation studies are required to examine the actual uptake of HIVST among young people. [ABSTRACT FROM AUTHOR]
